To Zlio/011i it may conce/fn.'

Be it known that I, FRANK HINMAN PrienroN'r, a citizen of the United States of Ame-rica, residing at Salfords, Horley, in the county of Surrey, England, have invented certain new and useful Improvements in Matrix-Case Equipments for Typographic Machines; and I do hereby declare the following to be a full, clear, and exact descrip'- tion of the same, reference being had to the accompanying drawings, forming part of this specification, and to the characters of refe-rence marked thereon.

This invention relates to matrix or die case equipment for type casting and similar typographie machines andre-fers t-o matrix cases in which the matrices are assembled in a frame in rows and columns. A matrix case of the kind referred to, as well as a machine in which it is adapted to be employed, is basically disclosed in United States Letters Patent No. 625,998, dated May 30, 1899. .ln such a matrix case the matrices are: oblong blocks, rectangular in cross section, one end being furnished with a character or formative cavity and the other end with a` centering cavity usually conical in shape for engagement with` a centering device for clamping and pressing each matrix against the mold when a cast is to be made. In the patented matrix case, the matrices are provided with lateral holes through their bodies for the accommodation of suspension rods, the construction being such that each rod suspends or supports a row of matrices. VwWhile these rods limit to some extent the lateral movements of the matrices of a row in one direction, they allow in the other direction the accumulated wear of a column of matrices to result in the displacement of any matrix of that column to a harmful extent. rlhey also permit matrices to turn or tilt in an undesirable manner.

rlhe main object of the present invention is to pro-vide means for limiting the side motion of an individual matrix in a direc tion parallel to the supporting' rods which pass through the openings in the bodies of the matrices; and to so construct the matrices and supporting bars therefor that a matrix or matrices can be removed and replaced without disturbing or interfering with the other matrices of the series. This Serial No. 693,854.

is accomplished in accordance with the present invention by the use of two series of parallel suspension bars or rods arranged at right anglesfto each other and having their ends resting in openings in the ma-l nection with the description of the invention as embodied in the accompanying drawings in which Fig. 1 is an inverted plan view of a matrix case embodying' the present invention.

Fig. 8 is an end elevation of one of the matrices, and Y Fig. 9 is an elevation of a matrix viewed second set in a direction at right angles to that sho-wn The matrix case con'iprises a frame Il Vof usual and welldnown construction` being box-like and having an opening through it for the accommodation of the matrices. On theV top of the frame 1 is a cover plate 2 provided with a series 'of perforations or vopenings 3 coinciding, when the matrices are assembled kin the matrix case, with the c entering cone holes t in the matrices 5 (Fig. 2).

The matrices 5 guiar iin cross section and furnishedv as hitherto witha characteror formative cavity 6 in one end and a conical centering cavity l in the other end. InY Fig. 1 for the sake of clearness, the character cavities have are oblong blocks, rectan- CII been omitted. For accommodating the suspension devices the matrices are conveniently provided or furnished on twoI of their exterior walls with transverse external parallel grooves 7; and at right angles to these grooves each matrix has a central transverse suspension opening 8 therethrough.

The two end walls of the matrix case are furnished with a series of openings 9, 10, and the suspension rods 11 are passed through the openings 9 and their inner ends caused to rest in the openings 10. The openings 9, 1() are in .line with the central openings S in the various rows of matrices when the latter are assembled in the matrix case 'frame 1, so that each bar 11 passes through the central openings off a row or" matrices (Fig. The bars 11 thus limit and control the lateral movement of the row or' matrices in' a direction at right angles to the said bars 11.

rllhe two side walls of the matrix case frame l are furnished with openings 12, 13 and the suspension bars 141 are passed through the openings 12, their inner ends resting in the openings 13. Each lbar 14 passes' between the matrices or' two neighboring columns and is accommodated in the external grooves 7 in the sides of the matrices of two neighboring rows or columns (Fie. 2 The bars 14 are approximately ot' a thickness or width equal to the depths of the grooves inthe two matrices which they support. These bars 1A limit the lateral movements ot the matrices in a direction at right angles to that controlled by the bars 11.

The method of suspension above described prevents the accumulated wear of a row or column of matrices from allowing a single matrix to become displaced to such an extent as to place it outV of register with the corresponding opening 3 in the protector plate 2, or so that the centering cavityt of the matrix cannot be entered by the usual centering device. The openings 9, 1() are on a. diti'erent horizontal plane from the openings 12, 13, and the bars 11 and 14, which are conveniently round, are furnished or -formed on their meeting sides with 'flattened parts 15, 16 (Figs. 4e to 7). rl`he fiat portions of the bars 11 and 1st thus bear upon each other and provide arrigid support for the matrices.

ln order to allow of the requisite vertical movement or a matrix relatively to the others when a cast is being made, the bars .l1 and 1% are of slightly smaller diameter than the openings 8 and grooves 7.

For convenience in removing all the bars of a. series together, the outer ends of the bars 11 are connected to or mounted in a )late or connecting bar 17 (Fig. t) which in assembled position lies close against one end of the matrix case frame and is retained there by a. suitable locking spring 18,Y One end ot the spring 18 is secured to an existing extension ofthe matrix case 'frame 1 and its free end bears against the plate 17. The plate 17 is furnished ,withV a notch 19 to receive the spring 1S when the latter has been dep-ressed and thus allow the bar 17 kand rods 11 to be removed.

Similarly, the bars lt are all connected to a plate 2O which, when the bars have been inserted into theholes 12 in the frame, lies close against one side member of the matrix case. O n the vupper surfaces ot' the bars 14 are formed shoulders 21 one pair to each bar, these shoulders being formed by interrupting the cutting of the flat surfaces 16, and one of the bars 11 passes between these shoulders and thus loclrs the entire series of bars 14 in position.

Then it is required to remove a matrix or matrices, the locking spring 18 is depressed and the bar 17 pulled away to withdraw the bars 11. rlhis releases the bars 14 and the plate 2O and they may next be withdrawn. This removal of both series ott bars frees thematrices anyone ot' which may be removed separately from the matrix case in an obvious manner.

I claim:

1. A matrix case comprising a frame, a series of matrices therein arranged in rows and columns, two series of suspension bars extending at right angles to each other to support the matrices and limit lateral movements of individual matrices, each series ot bars being supported in openings in the said frame, extending lengthwise of the bars whereby each series of bars may be witbdrawn or inserted in a direction lengthwise of the bars thereof through the frame openings therefor. 'Y

2. A matrix case comprising a frame, matrices therein having external side suspension grooves and transverse centra-l suspension openings at right angles to said grooves, two series of suspension bars supported in the frame at right angles to each other and engaging respectively the grooves and openings in the matrices and a connecting bar secured to each series ot suspension bars.

3. A matrix case comprising a frame, matrices therein` having external side suspension grooves and transverse central suspension openings at right angles to said grooves, two series ott suspension bars supported inr the frame at rightangles to each other and engaging respectively the grooves and openings in the matrices and a connect-ing bar secured to Yeach series ot' suspension bars, one series ot' bars being provided with locking shoulders to engage with one bar of the other series, whereby one series is locked by the other, and means for locking the last mentioned series in the said frame.
